removed by photosynthesis
dissolves in rainwater, seas, lakes
increasing due to human activity
contributing to global warming
produced when theres not enough oxygen present - incomplete burning
poisonous - drowsy, headaches, possibility to kill
produced when fuels burn incompletely
float around in atmosphere
fall back to ground and deposit as soot
comes from impurities in fuels when they are extracted from the Earth
when fuel burns, so does sulfur.
combine with oxygen to make sulfur dioxide, ends up in atmosphere
sulfur dioxide reacts with moisture in clouds to form dilute sulfuric acid (acid rain)
can cause lakes to become acidic, kills trees and damages statues eg limestone
can be removed from chimney flues by wetscrubbing with an alkali:
dissolved in seawater, producing carbon dioxide, water and dissolved sulfate.
2)calcium oxide slurry
slurry is sprayed onto gases and sulfur dioxide reacts with calcium oxide. calcium sulfite (s) waste product is formed.
formed when nitrogen and oxygen are exposed to very high temps eg in a car engine
once in the air, NO will go on to react with more oxygen forming nitrogen DIoxide
both react in air to produce dilute nitric acid (acid rain)
